The combined effect of phytostabilization and different amendments on remediation of soils from post-military areas
2019
Army bases and battle fields are areas of high pollution due to the chemicals released there. Soils in these areas suffer from these uses of the land, and ecosystem services are affected. Although, in the 20th century, the production of bombs and the locations of battle fields and army bases were widespread, there is little research on the impact of war on nature. Moreover, there is a need to rehabilitate the disturbed soils. The contents and ecological risks of Cu, Ni, Cd, Pb, Zn, and Cr in the topsoil from a post-military area (north-eastern Poland) were investigated. In addition, a vegetation experiment was performed with the technique of aided phytostabilization on soils from the study …
Microplastics in the global aquatic environment: Analysis, effects, remediation and policy solutions
2019
This opinion paper reports on Microplastics (MPs) pollution in the aquatic environment. MPs are a global problem being detected everywhere: marine environment, wastewaters, surface waters, soils, sediments, food and air. MPs can also absorb organic contaminants, and can be ingested by organisms and introduced into the food web. MPs can be a vector as well of pathogens whereas airborne fibrous MPs may enter our respiratory system with risk to the environment and humans. Main issues and gaps related to MPs on-going and future research are highlighted: chemical analysis, fate in wastewater and drinking water treatment plants, environmental and human health effects as well as remediation strate…
The contamination legacy of a decommissioned iron smelter in the Italian Alps
2018
The economically important activity of metal processing can tend to contribute to the degradation of the environment. Smelting is an important source of contaminants, dispersing large quantities of potentially toxic elements (PTE) and coproducts into the environment. Soils in the vicinity of smelters frequently contain high concentrations of PTE. In terms of the quantities processed, the major PTE are iron (Fe), aluminium (Al), copper (Cu), lead (Pb), manganese (Mn), and zinc (Zn); of these Cu, Pb and Zn are, potentially, highly hazardous elements. The general problem addressed by this study is to determine if the PTE concentration in the soils of an area downwind from a decommissioned iron…
An assembly of organic-inorganic composites using halloysite clay nanotubes
2018
Halloysite is natural tubular clay suitable as a component of biocompatible nanosystems with specific functionalities. The selective modification of halloysite inner/outer surfaces can be achieved by exploiting supramolecular and covalent interactions resulting in controlled colloidal stability adjusted to the solvent polarity. The functionalized halloysite nanotubes can be employed as reinforcing filler for polymers as well as carriers for the sustained release of active molecules, such as antioxidants, flame-retardants, corrosion inhibitors, biocides and drugs. The tubular morphology makes halloysite a perspective template for core-shell metal supports for mesoporous catalysts. The cataly…
Sensibilización de género en la traducción a través de TAV y publicidad
2020
El objetivo de esta investigación es describir un estudio piloto realizado con 46 estudiantes de Traducción y Mediación Intercultural en un módulo de lengua inglesa nivel avanzado. Adaptamos el modelo de conciencia intercultural de Borghetti y Lertola (2014) mediante la subtitulación, una modalidad de TAV (Traducción Audiovisual) para abordar cuestiones de género y lenguaje en relación con el género en relación con la subtitulación de un anuncio de gel corporal de Old Spice. Los resultados muestran que nuestros estudiantes no consiguieron transmitir de manera satisfactoria el mensaje sexista del anuncio en su paso al castellano, lo cual se pudo confirmar al comparar la traducción de nuestro…
Modelling biological and chemically induced precipitation of calcium phosphate in enhanced biological phosphorus removal systems
2011
The biologically induced precipitation processes can be important in wastewater treatment, in particular treating raw wastewater with high calcium concentration combined with Enhanced Biological Phosphorus Removal. Currently, there is little information and experience in modelling jointly biological and chemical processes. This paper presents a calcium phosphate precipitation model and its inclusion in the Activated Sludge Model No 2d (ASM2d). The proposed precipitation model considers that aqueous phase reactions quickly achieve the chemical equilibrium and that aqueous-solid change is kinetically governed. The model was calibrated using data from four experiments in a Sequencing Batch Rea…
Adolescent Sexual and Emotional Development: The Role of Romantic Relationships
2015
Abstract The physiological processes occurring during adolescence, often so abrupt, threaten the permanence of the previously constructed sense of identity, questioning the patterns and representations that had governed the relations of the teenager with his body and with his relational systems. Although puberty is not only reduced to sexual transformations, definitions centered mainly on this aspect can be found in the literature. In fact, pubertal development is the acquisition disclosure index of adult reproductive capacity. Objective Explore the process of increasing involvement of the adolescent in an emotional and sexual relationship with a partner. Methodology: It will try to underst…
Dynamic Performance of the Agricultural Sector Under Conditions of Climate Change and Armed Post-conflict
2018
The agricultural sector is a strategic source for the sustenance of the population worldwide, however, given the lack of a favourable environment that guarantees its sustainability and growth, this sector is exposed to multiple conflicts and needs, which affect its performance and even causing desertion of the producer. In this research, we model and analyse the agricultural sector of the potato in the Colombian context, which in addition to being a strategic food to respond to food crisis, represents the needs of the agricultural sector, where about 90% of producers are classified as small because of their low participation in land tenure and where, in addition to the low level of technolo…
Heavy Metals and Human Health: Possible Exposure Pathways and the Competition for Protein Binding Sites
2021
Heavy metals enter the human body through the gastrointestinal tract, skin, or via inhalation. Toxic metals have proven to be a major threat to human health, mostly because of their ability to cause membrane and DNA damage, and to perturb protein function and enzyme activity. These metals disturb native proteins’ functions by binding to free thiols or other functional groups, catalyzing the oxidation of amino acid side chains, perturbing protein folding, and/or displacing essential metal ions in enzymes. The review shows the physiological and biochemical effects of selected toxic metals interactions with proteins and enzymes. As environmental contamination by heavy metals is one of the most…
Can Interactive Mediation Tools Bridge the Identity Gap Between the Public and the Art Museum?
2015
International audience; Consumer behaviour in the field of art museums appears to be influenced both by the identity of the public and the art museum and by the context. It is a matter not of changing museum content, but of bringing its identity closer to that of the public in order to promote access to art. The authors first present the theoretical and conceptual framework for their research and then suggest a qualitative methodological approach to addressing the issues described in the results.; La conducta del consumidor en los museos de arte parece estar influenciada tanto por la identidad del público y del museo como por el contexto. No se trata de cambiar el contenido del museo, pero …
